Introduction

  • ✔ This project presents a Next Word Prediction application
  • ✔ Developed using R and Shiny
  • ✔ Provides intelligent and context-based word suggestions
  • ✔ Demonstrates key Natural Language Processing concepts

Key Idea: The application predicts the next word based on learned text patterns.

Problem Statement

  • ✔ Typing complete sentences can be time-consuming
  • ✔ Users require quick and relevant suggestions
  • ✔ Objective: Predict the most probable next word
  • ✔ Improve typing efficiency and user experience

Key Idea: Faster prediction enhances user productivity.

Model & Method

  • ✔ Uses a bigram-based language model
  • ✔ Extracts the last word from user input
  • ✔ Matches patterns from trained dataset
  • ✔ Applies frequency-based ranking
  • ✔ Outputs best prediction and top 3 suggestions

Key Idea: Predictions are based on frequency of word occurrence.

Application Demo

  • ✔ User enters text (e.g., “I love”)
  • ✔ App predicts next word (e.g., “coding”)
  • ✔ Displays best prediction and alternative suggestions
  • ✔ Designed with a clean and interactive interface

Key Idea: Simple interface with fast and meaningful output.

Conclusion

  • ✔ Successfully built a word prediction system
  • ✔ Deployed as a Shiny web application
  • ✔ Provides quick and relevant suggestions
  • ✔ Can be improved using larger datasets and advanced models

Key Idea: Demonstrates a practical application of NLP concepts.
